San Francisco was booming in the mid-nineteenth century, and along with adventurers seeking their fortunes came sacks of green coffee beans. The old Yerba Buena Cove swiftly filled with ships, and the city emerged as the third-largest coffee port in the United States. What followed was the rise--and local demise--of the "big three" coffee roasters: Folger's, Hills Brothers and MJB. Specialized Bay Area roasters like Peerless, Peet's and Blue Bottle sprang up in their wake, while places such as Tosca's, Caffé Trieste and the Blue Unicorn blazed the way for modern coffeehouses. Join author Monika Trobits as she traces the historic voyage of the humble coffee bean to the shores of San Francisco Bay.
